HARRY E. CLOVER, 0F ELKHART, INDIANA.

REGISTER.

Application led September 21, 1915.

To all whom t may concern.'

Be it known that I, HARRY E. CLovnR, a citizen of the United States, residing at Elkhart, in the county of Elkhart and .State of Indiana, have invented certain new and useful Improvements in Registers, of which the following is a specification.

This invention relates to improvements in registers for hot air heating and circulating systems, one object of the invention being to provide a register1 of simple construction which eectually obviates chilling of the heated air by contact with cold surrounding walls or surfaces.

A further object of the invention is to provide a register which embodies a novel and improved construction of valve or shutter for controlling the discharge of the heated air.

A still further object of the invention is to provide a construction of register which, by a slight modiiication, may be combined with another register to form a double register, whereby air from a common conductor may be discharged into opposite rooms or apartments.

The invention consists in the features of construction, combination and arrangement of parts hereinafter more fully described and claimed, reference being had to the accompanying drawings, in which:

Figure 1 is a central vertical front to rear section through a hot air register embodying my invention; Fig. 2 is a vertical transverse section through the same on the line 2-2 of Fig. 1; and Fig. 3 is a sectional view similar to Fig. 1, showing two registers embodying the invention assembled to form a double register.

The register comprises an outer shell or casing 1, preferably of rectangular or oblong rectangular form, which is of box-like conformation. This body 1 has an outlet 2 at the front, which is covered by a perforated or slotted face plate 3, which is of any suitable construction and is secured in place by screws or other-suitable fastenings 4. The lower edge of this plate 3 may rest against a iianged abutment or supporting strip 5, which has its tia-nge extending forwardly from the base of the flue opening. Below the outlet 2, the front of the outer casing is provided with a short front wall 6, which is provided at the base of the opening with an inwardly extending flange 7 which forms an abutment against which closes the Specification of Letters Patent.

lower free edge of a shutter or valve 8. This shutteror valve, which is preferably in the form of a curved sheet metal plate, is hinged or plvoted at its upper edge to a cross pin 9, so as to swing between the abutment 7 and the rear wall of the casing, so as to control the passage of the hot air through the register. The shutter or valve is engaged at one edge by the forked portion 10 of a pivoted adjusting lever 11, having a finger piece 12 projecting outwardly through one of the slots or perforations in the face plate 3, whereby the shutter may be adjusted as required. The finger piece of the shutter may be arranged to engage a suitably constructed notched keeper 13, Vby means of *whichv theV shutter may be held in position to close the outlet 2 against the passage of the hot air' into the room or apartment. When the shutter is swung to the open dotted line position, shown inV Fig. 1, in which it opens communication between such inlet and the outlet of the casing, it may be 'locked in such position by the notched keeper by proper adjust-ment of the latter.

In accordance with my invention, the register is made of double-walled construction, and includes an inner shell or casing 14,- whereby an air circulating space 15 is formed .between the inner and outer walls of the device. Passages or perforations 1G are provided in the top and bottom walls of the casing and communicate with the space 15, and the walls of the inner casing are secured and held in properly spaced relation with respect to the outer casing by screws or other similar connecting fastenings 17. The spaces or passages l5 thus provided serve to permit of the iiow of air between the inner and outer casings, which air is cooler than that supplied through the heating system but isheated to some extent by conduction from the pipes and registers, by which the hot air is prevented from becomino chilled from walls or other portions i topV of body and at its lower edge is bent inwardly to form the bottom wall of the space 15, thence bent upwardly in the form of a flange 21 lying on the inside of the wall 19, and then, like the iront and side walls of the outer easing of the body, each of which is provided with a ange 21 like the flange 21, is bent downwardly within the inlet opening 22 formed at the base of the body to provide a retaining flange 23, all oi the walls of the body at the base having similar iianges 23 which are provided to form 5, with the flanges 21 grooves to receive the upper edge of the hot air supply pipe section 24 and to clamp such edge oi the said pipe section in position. In Figs. 1 and 2, which show a simple single radiator structure, the top of the outer casing is provided with an outlet opening 25 and a iange or collar 26 to respectively communicate with and receive the lower end of the discharge pipe section 27. It will thus be seen that the register may be easily and conveniently iitted within its receiving opening in the wall of a room and between and engaged with the pipe sections 24 and 27, and that a space will belefb for the circulation of air through the flue and channels 15 for the purposes described, where, by the adjustment of the shutter 8, the iow of air to the room or apartment supplied by the register may be easily and conveniently controlled.

In Fig. 3 of the drawing, I have shown the use and arrangement of the device whereby two single radiator sections may be connected and employed as a double radiator, for use in a wall or partition between adjoining rooms for the purpose of supplying the latter with air from a common flue. To adapt the registers for this purpose, the top walls of the registers are left intact or imperforate, while the double rear walls of the registers are removed by disconnecting the fastening screw 17, allowing the open rear portion of one register to be fitted within the other and the enlarged supply pipe section 2liEL to be fitted within the lower base portion of the double register. The mode of use of this double register will be readily understood from the foregoing description.

Having thus described my invention, I claim:

1. A register comprising a boXlike body, having an opening in its front wall, and an inlet at its bottom, said body comprising an outer casing and an inner casing having their walls arranged in spaced relation, the top and bottom walls of said body being provided with perforations tor the free circulation of air into and through the space between the casings, and means for controlling the opening in the front of the body.

2. A register comprising a box-like body formed of spaced innerand outer walls, said body having an opening at the front and an inlet at the bottom, and provided also with openings communicating at top and bottom with the space between the walls of the casing, the bottom walls of the body being formed by portions bent from the outer casing, said bottom walls having portions projecting upwardly inside of and parallel with the walls of the inner casing and having said portions provided with downturned retaining flanges disposed within said bottom inlet to provide clasps to receive and hold the end of a conductor. Y

In testimony whereof I aiiiX my signature in the presence of two witnesses.
